Square Enix recently expanded its official Japanese website for its Game Boy Advance title Kingdom Hearts: Chain of Memories. The static introduction screen has been replaced with interactive features promising fun for anyone who can operate a mouse and read Japanese.

In addition, Square Enix has explained the use of cards in the game's battle system. While Sora beats the stuffing out of enemies, enemy cards will emerge on the screen. Players can stack the same cards to create powerful attacks or play other cards to summon allies in the heat of battle.

Kingdom Hearts: Chain of Memories is expected to be released sometime next year in Japan. A North American release has not been announced.
